a few notes on raid5....the drives (at least per my research) have to all be of the same size...you can't have 2 40 gig drives and 1 120 gig drive and have raid5 work...another note is that you can't just instate raid5 (or any of the higher level redundant raid levels)....you have to start from scratch...which would mean you'd have to reinstall windows etc.. after the array was built
I understand they all have to be the same. Currently I have 2x 250GB 7200.10 Seagate hard drives, and I am able to purchase more of the exact model drives for what I believe to be rather cheap.
I also understand that once the RAID is achieved, I would then need to install Windows and move everything back on to the drives again. I see no reason why I won't be able to make a full backup, and then "restore" the backup onto the RAID drives once everything's setup?
So what's your opinion on which RAID variant to go, anyway? Would RAID 5 be a good option? I am open to other ideas if I can find a recommended quality RAID card at a good price for my budget. Something that will be for the geek in me to triumph over!
Windows should see it as just a large hard drive, right? Maybe it's a bit more technical than that (like Windows knowing there's x
drives in a RAID setup under Disk Management or something), but under Computer it will report one drive?
It would be good if I could check out somebody's RAID setup already to get a better idea on it.*troy wanders off to the local university...
RAID 1 is supposedly the more secure option if you do want a RAID setup because its basically a mirror image, and some implementations of this will rebuild it for you as well - this is specified with redundancy built into it.
RAID 1 is not an option in my opinion. I don't want to have two hard drives doing exactly the same thing. While this would be a redundancy option, I don't like that you've got two hard drives for only one hard drive's space. I might as well run RAID 1 from my motherboard RAID options.
Or am I wrong in thinking that 4x 250GB drives in RAID 5 will give me (give or take) 1TB of disk space?
And what did you mean by some
implementations will rebuild it? If one drive dies, then shouldn't you be able to add another drive and have it rebuilt by all
implementations? If it's RAID 1, then you'll still be able to access your stuff with only one drive (right?), but then you'd have to back the whole lot up elsewhere and then format the original and the new one to a RAID 1 solution again. Sounds dodgy...
Many thanks for your responses, though. This is rather interesting, even if I end up doing nothing about it... I'm definitely going to do some more research on it, anyway. Got any known good links you recommend? Of course I'll be checking "Google"!
P.S. Yeah yeah yeah, I know this is way overkill! You don't need to mention that again...
